easyTanya drove on the highway and on local roads to complete a trip of 290 miles. The drive took 5 hours. She drove an average speed of 65 miles per hour (mph) on the highway and an average speed of 30 mph on local roads. If x is the time, in hours, Tanya drove on the highway and y is the time, in hours, she drove on local roads, which system of equations represents this situation?
A
65x+30y=5
x+y=290
x+y=290
B
65x+30y=290
x+y=5
x+y=5
C
30x+65y=5
x+y=290
x+y=290
D
30x+65y=290
x+y=5
x+y=5
